Coral reefs are considered by many as one of the worlds most magnificent natural wonders; vibrant underwater landscapes housing diverse species of marine fauna creating beautiful and complex underwater ecosystems. They play a crucial role in maintaining marine biodiversity and supporting human economies and as such their preservation is vital for the health of our oceans and the well-being of countless species including man-kind.
Scuba divers have been marvelling at the beauty of these underwater ecosystems for generations and as such have created a thriving industry for reef tourism in tropical and sub-tropical coastal communities. I have been lucky enough to personally visit three of the largest reef diving hotspots globally, The Mesoamerican reef, The Coral triangle and The Great Barrier Reef. All three ecosystems are vast and can be largely varied depending on specific geographical location visited, however there are common trends present in each ecosystem with one of the most obvious being the commitment to conservation, education and research.
Coral monitoring techniques can vary depending on institution level, however citizen science surveys allow for mass data collection with standardised methodology across multiple locations allowing for vital insight into the health of the global reef systems, in particular ecological importance after the 4th global mass bleaching event experienced in April 2024, allowing for a wealth of data available for decision making authorities. A great example of global surveillance is Coral watch, developed by The University of Queensland as a universal worldwide survey technique that has been adopted in 79 countries.
For recreational divers participating and learning scientific survey techniques can enhance the dive experience by allowing divers the opportunity to contribute to the preservation of ecosystems they are passionate about and share this knowledge with a wider audience, increasing the uptake in coral reef conservation as topics in discussions for a larger audience, essential for raising awareness about the ecosystem due to its geographical isolation. Furthermore increasing knowledge of species present allows for an increased level of socialising as post dive participants are able to engage in discussion with buddies and dive leaders about what was spotted on the dive and increases awareness in the variety of reef ecosystems when travelling to new dive locations.
Here at Gili Shark Conservation these courses are available to participants during the research assistant programme through conservation diver, and PADI scientific diver, along with participating in various citizen science surveys including Coral Watch, in-house roving diver surveys and coral restoration projects and I have first hand enjoyed the benefits of widening my perception of the underwater world and sharing this experience with other ocean enthusiasts through citizen science.
